MOTOR FOR BABY-ROCKERS.

SPECIFICATION formingpart of Letters Patent No. 613,037, dated October25, 1898.

Application filed January 8, 1898.

To @ZZ wir/0m it may concern.-

Be it known that I, PERRY A. HERRINGTON, a citizen of the UnitedStates,residing at Hematite, in the county of Jeiferson and State ofMissouri, have invented a new and useful Motor for Baby-Rockers, ofwhich the following is a specification.

This invention has relation to means for rocking or vibrating a body,such as a babycarriage or cradle, and which may be used for operatinglight machinery, such as a fan, churn, or sewing-machine.

One of the principal features of the invention is to provide a motor ofimproved construction to be run by weight and in which the train ofgearing, including the governor and frame, is disposed so as to reducethe friction to a minimum amount and enable the individual parts to bereadily accessible for cleaning, oiling, and repairing.

For a full understanding of the merits and advantages of the inventionreference is to be had to the accompanying drawings and the followingdescription.

The improvement is susceptible of various changes in the form,proportion, and the minor details of construction without departing fromthe principle or sacricing any of the advantages thereof, and to a fulldisclosure of the invention an adaptation thereof is shown in theaccompanying drawings, in which- Figure 1 is a detail view showing theinvention applied to a baby-carriage for imparting a rocking orvibratory movement thereto. Fig. 2 is a front view of the motor. Fig. 3is a side view thereof. Fig. 4 is a detail view of the governor. Fig. 5is a detail view of the ratchet-and-pawl mechanism between the drum andthe gear-wheel mounted loosely on the shaft thereof. Fig. 6 is a detailview of the drum, its shaft, and the parts intimately connectedtherewith.'

Corresponding and like parts are referred to in the followingdescription and indicated in the views of the drawings by the samereference characters.

The means for supporting the working parts of the motor consist of ahorizontal frame 1, of oblong form, mounted upon legs 2, and a verticalframe 3, which is secured at its lower end to the side bars of thehorizontal frame,

Serial No. 666,107. (No model.)

and this vertical frame has an inwardly-extending arm 4, whichcooperates with the governor in the manner presently to be described, soas to check the speed of the motor in the event of the latter exceedinga predetermined number `of revolutions per minute. A bracket-arm 5 issecured to an end of the horizontal frame 1, and a lever 6 is fulcrumedabout midway of its ends to the upper ex 6o tremity of the arm 5 and iscounterbalanced by being provided with a weight 7 at its upper end. Acrank-shaft 8 is connected by means of a pitman 9 with the lower end ofthe lever 6 and transmits motion thereto from 65 the train of gearing.

The winding-shaft 10 is journaled at its ends in the side bars of thehorizontal frame 1, and one of its ends projects and is made angular toreceive a key or crank, by means 7o of which the motor is wound up.Adrum 11 is secured upon the winding-shaft, so as to turn therewith. Thedriving-gear 12,mounted loosely upon the shaft 10, between the inner endof the drum 11 and a collar 13, is provided 75 outer end of the pawlbeing expanded, so as 8o to obtain an extended bearing against the inner periphery of the ring 14. This pawl 1G has its inner end pivoted ina groove or notch in a side of the collar 13, and a spring 17, in-

terposed between the pawl and collar, holds the outer end of the pawlagainst the inner surface of the ring 14, thereby maintaining said pawlin operative relation. A cord, rope, or chain 18 is secured at one endto the drum 11 and passes upwardly over a pulley 19 at the 9o upper endof a standard 20, secured to a ta ble or support 21, and is weighted atits free end, the weight 22 being sufficiently heavy to operate the partto be driven. Agearwheel 23, secured upon the crank-shaft 8, is in meshwit-h the train of gearing, actuated by means of the weight anddriving-gear 12, and likewise intermeshes with a pinion 24, secured to avertical shaft 25.

A plate or disk 26 is secured to the upper end roo of the shaft 25, andweighted arms 27 have pivotal connection therewith at diametrically op-vtional engagement with the inner end of the' arm 4, thereby retardingthe speed of the motor. The lower face of the sleeve 28 is ofapproximately conical form, whereby the frictional contact between itand the arm 4t may be increased proportionately to the outward tendencyof the free ends of the arms 27. The inner end of the arm 4t is formedwith a circular opening to receive the lower conical end of the sleeve28, thereby providing for the wedging of the said sleeve into theopening, so as to insure a checking of the motor should it tend toexceed a predetermined speed.

Inasmuch as the motor is designed, primarily, for rocking or oscillatinga baby-car- -riage it is shown in this connection, although it isobvious that it maybe employed for other purposes and for driving anylight machinery. In order that the body of the carriage may beoperatively connected with the actuating mechanism, a clamp 29 isprovided, and the upper portion of the carriage-body is gripped betweenthe jaws of the clamp, the latter being provided with an arm having ajournal 30, which makes pivotal connection with the outer end of a rod3l, by means of which the clamp is connected to the lever 6.

The motor being suitably mounted is rendered operative by winding theweighted cord or the like upon the drum 11, and the rod 3l being engagedwith the journal 30 of the clamp 29 the lever 6 will be vibrated by theaction of the motor and the running down of the weight 22 and impart arocking or vibratory movement to the carriage-body,

A sleeve 28 is slidably mounted A provision being had for such movementby the spring connections between the carriagebody and the axles commonin this class of devices. The motor can be readily disconnected from thecarriage by slipping the outer end of the rod 3l from off the journal 30or removing the clamp 29 from the carriagebody, as desired.

Having thus described the inventiomwhat is claimed asnew, and desired tobe secured by Letters Patent, is-

1. In a train of gearing, the combination of a vertical shaft in meshwith the train of gearing and driven thereby, weighted arms havingpivotal connection intermediate of their ends with the shaft androtatable therewith, a sleeve slidable upon the vertical shaft andhaving its lower end made conical, vertical links connecting the innerends of the weighted arms with the said sleeve, and an arm secured atone end to the frame and having its other end terminating between.theends of the vertical shaft and having a circular opening to receive thelatter, the free end of the arm receiving the frictional impact of theaforesaidvsleeve, substantially as and for the purpose set forth.l

2. In combination, a train of gearing comprising a governor, acounterbalanced lever actuated by means of the train of gearing, a clamphaving a journal, and a rod adapted to connect the journal of the clampwith the weighted lever, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
